I'm not sure there's ever a printable calendar, and at this point it's so long it would take up a number of pages. But here are some of the races Cycling.TV lists in their "Live Races" tab for 2008:
Kuurne-Brussels-Kuurne
Paris-Nice
Tirreno-Adriatico
Milan-San Remo
Dwars Door Vlaanderen
E3 Prijs Vlaanderen
Brabantse Pijl
Dreidaagse de Panne
Ronde Van Vlaanderen
Pais Vasco
Gent-Wevelgem
Paris-Roubaix
Scheldeprijs
Amstel Gold
Tour de Georgia
Fleche Wallonne
Liege-Bastogne-Liege
Tour de Romandie
Rund um den Henninger Turm
Giro d'Italia
And that's as far as I got, page 5 of 10, before the interface refused to show me the rest of the calendar. Page 6 returns you to page 4, and hitting "next 20" gets you back to January. So it's still the same old bug-fest. But Anthony and Brian are fab and usually the bugs go away in time for the action. The only exclusion of note is Het Volk, of all things, but they ran it in 2007, so perhaps negotiations are ongoing. De Ronde wasn't on the list last I checked, so even this has been taken care of. Happy new year!
